Fig. 1 in Specialized diterpenoid metabolism in monocot crops: Biosynthesis and chemical diversity

Fig. 1. Size and functional diversity of diterpene synthase families in Poaceous crops. (A) Genome size (grey) and number of demonstrated or predicted diterpene synthases (diTPSs; black) in selected Poaceous crop species. Genome sizes were retrieved from public repositories (https://phytozome.jgi.doe.gov/; https://www.maizegdb.org/; http://www.gramene.org/). (B) Presence of functionally characterized Poaceous class II diTPSs involved in general (black circles), specialized (white circles), and general and/or specialized (grey circles) metabolism. Triangles represent class I diTPSs shown to function in combination with individual class II diTPSs in in vitro or in vivo activity assays.
